ANTONINUS FARINA, OF NEWV YORK, N. Y., ASSIGNOR, BY MESNE ASSIGN- I MENTS, TO PETRINA FARI NA, OF SAME PLACE.

APPARATUS FOR MAKING BOOT OR SHOE HEELS.

SPECIFICATION forming part of Letters Patent No. 393,892, dated December 4, 1888. Application filed April 5, 1888. Serial No. 269,653. (No model.)

To all whom it may concern.-

Be it known that I, ANTONINUS FARINA, of the city, county, and State of New York, have invented a new and useful Improvement in Apparatus for Making Boot or Shoe Heels, of which the following is a full, clear, and eX- act description.

This invention relatesto an improvement in means for making heels for boots or shoes by forming a heel-shaped leather shell and filling the shell with a solid body. The shell 'has been heretofore generally made by pressing a moistened piece of leather into shape in a mold of appropriate form but it is extremely difficult in this way to produce an outwardly-concave heel-shellas for the heels of womens shoeswhen leather of any great thickness is used.

My invention consists of novel devices, substantially such as those hereinafter described and as claimed, for stretching and pressing the leather into the approximate form of the finished shell preparatory to molding it, and also for molding and working the leather into the .final shape thereafter.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved devices for stretching and working the leather preparatory to molding it. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3'is a cross-sectional elevation of the same on the line :20 m, Fig. 2. Fig. 4 is a cross-sectional elevation of a part of the same, taken on the line '31 y, Fig. 1. .Fig. 5 is a plan view of the.

improved finishing-mold. Fig. 6 is a longitudinal sectional elevation of the same on the line .2 ,2, Fig. 5, andits mounting for finishing F, extending therethrough adapted to fit and receive the part of the post 0 above the shoulder D, and with a socket, F, in its bottom to receive the corresponding part of the post C, and on the threaded end of the post 0, projecting above the core, a nut, 0 is screwed down tightly, so as to hold the core immovable on but slightly elevated from the base B.

The strip of leather A to be worked is cut of a somewhat greater width than the depth of the core E, and when moistened is wrapped around the curved back and sides of the core, so as to project slightly beyond the lower edge thereof, which edge will bite into the leather and prevent it from slipping when being stretched. A cover-plate, E, is adapted to be held down upon the top of the core by the nut C and to project beyond the core, so as to prevent the leather from working upward.

The free ends of the leather strip projecting beyond the breast of the heel are adapted to be seized by a grip, G, consisting of an outwardly-tapering rectangular nut, H, having series oftransverse corrugated teeth H on each of its four sides, forming jaws, a U- shaped head, L having the inner faces of its arms I tapered and transversely corrugated to form jaws corresponding to and adapted to engage with those on opposite sides of the nut H, and a handled screw-bar, J, threaded to work lengthwise in the correspondinglythreaded nut H, but adapted to slide loosely in the jaw-carrying head I. The head I is made in two longitudinal sections, each carrying one of the jaws, I and formed with opposite neck-sections 1 around which is placed a collar, 1 carrying a set-screw, I, for binding the two neck-sections l and hence the head-sections, together as a united whole.

The screw-bar J is mounted to turn and slide freely in a tubular boss,. raised on the base B to allow the free ends of the leather strip to be readily placed,respectively,between the corrugated jaws 011 opposite sides of the nut H and the corresponding jaws on the head I, and on screwing the bar J against the core as a bearing the nut H will be retracted, first gripping the leather firmly between the jaws on the same and the head I and then drawing on the leather so as to stretch it tightly around the core and cause it to take the form of the back and sides thereof. The ends of the leather st rip can be readilydetached from the grip G on loosening the set-screw T withdrawing the collar 1 from the neck-sections and separating the jaws I from the nut. As

5 it then becomes necessary to bend and join the ends of the leather strip over the fiat breast of the heel-core, a clamp, K, is provided for binding the leather to the back and sides of the core, so that the stretcher can meanto while be removed and the core E taken ott the base l by removing the fastening-nut leaving the ends of the strip A tree.

The clamp K is formed mainly of a threaded handle-bar, L, a threaded nut, N, working on the threaded handle-bar, and laterally-swinging jaws N, pivoted to opposite sides of the nut M. The inner end of the bar L is formed with a neck, ll, mounted to turn loosely in the socket ot' a bearing, I which is formed with a bearing-face conforming to the back of the core to adapt it to be pressed against the leather on the back of the core E without and a set-screw, S", is mounted in said catchmarring the leather.

The swingingjaws N have presscr-hcads X, the inner ti'aces, N of which are shaped conversely to the side of the core E to adapt them to bear with uniform pressure on the leather on each side of the same, but have their rear edges slightlybeveled to avoid marring the leather.

The jaws X are formed medially with corresponding inset necks 0, around which a yoke, 0, having an end slot, and T-shaped locking-piece 0 therefor, is adapted to be passed to lock the jaws together, the lockingpiece ()bcing provided with an adjustingscrew, 0 working therethrough against the mold-section, removed trom the mold, thereby neck of the adjacent jaw Nt'or drawing the jaws together and clamping the leather tightly 40 upon opposite sides of the core.

The screw-bar l, is adapted to be then screwed forward in the nut M to press the bearing I. firmly against the leather on the I serving as a handle, the free ends of the leather trimmed oti, bent over the breast of The grip G can then be the core by hammering, and scart'cd or otherwise prepared for joining without removing the core. The leather shell having been in this waybrought to an approximately-tinished its front edge, erect parallelbearings Q fixed 3 to opposite sidcsof the bottom, an erect bearing, Q, fixed to the rear of the bottom, and a removable t'ront bearing, Q to receive and hold the ends of which vertical grooves Q are formed in the inner faces of the side bearings,

Mold-sections R, conforming interiorly to shape, the clamp K is removed and the leather 3 the sides and backot' the heel, are adapt ed to slide loosely on the bottom Q of the mold toward and from each other, and a mold-section, R, conforming interiorly to the breast of the heel, as indicated in dotted lines in Fig. ti, is also placed loosely on the bottom Q in front of the side mold-sections, R, the arrangcn'ient being such that the leather shell with its core E will exactly lit within the inner faces of the mold-sections when brought together, as in Fig.

Followers S are mounted to slide in transvcrse grooves S, t'ormed in the bottom Q, against and with the side mold-scctions, R, a guide-bar, S being pivoted to the top of one side bearing, Q and adapted to swing across to the opposite side bearing, so as to lie in grooves 5, formed in the tops of the followers 5, and hold the same against lateral or vertical displacement. An L-shapcd catch-plate, S", is secured to the latter bearing (2* to engage the free end of the swinging guide-bar,

plate Fol-locking the said guide-bar in place.

Adjusting-screws T are mounted to work lengthwise in the opposite side bearings, Q, against the respective followers S, and an adj usting-screw, T, in the removable t'ront bean ing, Q", against the breast mold-section R, so that by properly turning said screws and blocking the rear ends of the side mold-sections, as shown, the heel-shell can be pressed evenly and tightly upon the core by means of. the embracing mold-sections. \Vhen such pressure has been applied for the required length of time, the trout: adjlisting-screw, T, is loosened and the bearing Q", with the breast exposing the joint in the breast of? the shell.

A mounting, as that shown in Fig. ti, is provided, having open side bearingsd', to receive removable trunnions l,",which are Formed on opposite sides of the mold I, so that the said mold can be swung to the verticalposition shown in dotted lines in Fig. I to bring the shell-joint at the top in convenient position for working and tinishing.

A spring or springs, l"-, are connected with thetront of the mold and with the base of the mounting to normally hold the mold in a horizontal position, a rest, 1", being arranged to stop the mold in turning to such position. A springactuated lever, L, is pivoted also to the base of themountingin position to engage and lock the mold I when in its vertical position, as indicated in dotted lines. The adhesive substance for uniting the ends of the f shell, it scat-fed, or an interior U-shaped fast citing-tack may be then applied, and the filling,which may be of wood,leather, or other ,appropriate substance, having been introduced, the pressure of the mold is again applied to complete the heel in the usual way.

This application has reference particularly to the apparatus herein shown and described for carrying out the process set forth;

but I hereby reserve the right to at some proper time hereafter apply for a patent on the said process.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
